ROBERT CAIRN$ AND JOSEPH W. CAIRNS, OF WATERTOWN, WISCONSIN.

COIN- DELIVERY MACHINE.

Application filed July 24,

To all whom it may concern:

Josnrrr W. CAIRNS, citizens of the United States, residing at Watertown, in the county of Jefierson and State'of vVisconsin, have invented new and useful Improvements in Coin-Delivery Machines, of which the following is a specification.

This invention relates to-"change-making and other coin-delivery machines, and more particularly to the mechanism for selectively .operating the coin-ejecting devices, the obj ect of the invention being to provide anovel and improved electrically operated mechanism which can also be operated manually.

The object stated is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawings forming a part of this specification.

In the drawings, 7

Figure 1 is a side elevation of the machine;

Fig. 2 is a front elevation thereof;

Fig. 3 is an enlarged cross section;

Fig. 4c is a diagrammatic section on the line 4L4 of Fig. 3, and

Fig. 5 is a section on the line 55 of Fig. 3, a fragment only of the mechanismbeing shown;

Referring specifically to the drawings, 10 denotes the casing ofthemachine, the same being construotedand equipped with suitable supporting means for the various elements which make up the coin-delivery mechanism. The front of the casing has a plurality of coin chutes 11 designed to support coins of different denominations in With each coin chute is associated an ejector 12 for pushing the bottom coin from beneath the stack. The ejector 12 is carried by a slide block 18 mounted on a guide stem 13*, and connected by a link 14 to one arm 15 of an angle lever having its other arm 16 connected by a link 17 to a bracket arm 18 on a'reciprocatory stem19 working between guide rollers 20. The, angle lever is fulcrumed, as shown at 21, to a support 22 in the casing 10. The ejector device .-is disclosed in. the application filed June 17, .1920, Serial No. 389,651, and hence a further description thereof in the present'application is not necessary. It willbe apparent that the ejector 12 is advanced to deliver a equipped with asst-em 19.

coin when "the stem 19 moves downwardly, Be it known that we, ROBERT CAIRNs and and on the return stroke of theiste'm, the

ejector is retracted.

ing its stem 24 fitted witha cross bar 25 pro vided with one or'morerlugs 26 adapted to engage a corresponding number of longitudinal bars 27, each of which latter is The machine is shown provided with one hundred keys for making change from one cent to one dollar, and one extra key to deliver a single dollar. When a key 23, corresponding invalue to the desired change, is depressed, the bar 25 on the stem of sa-id key, through its lugs 26 depresses the bars 27 in the path thereof, andthe latter through the stems 19 and the connections hereinbefore described, operate the ejec-tors 12 required to eject the desired amount. As this selector'mechanism is well known in the art, a further description there of is not necessary. The bars 27 work and are guided at their ends in slots 28 in guide bars29. .1

Thusfar described the apparatus is operated manually by depressing the keys 23. The apparatus is also'provided with a means whereby it may be operated electrically at will. This means will now be described.

Alongside each bar 27 is positioned a parallel auxiliary bar 30 which is in the path of auxiliary lugs 31'so as to be actuated thereby when the keys 23 are depressed, these lugs being on the cross bars 25 of the key stems 24. Thus, when the keys 23 are depressed the bars 27 as well as the bars 30 are pusheddownwardly. The bars 30 however are not provided with stems 19 for actuating the ejectors 12, but instead, each bar 30 has a depending rod 32 passing through a spring 33 hearing at one end against an abutment, 34: on the rod and seating at its other end ona support 35. These springs are for the purpose of givingthe bars 80 a return stroke after they have been depressed. Similar springs-36 are provided for the bars 27, the same being coiled around the stems 19. Each stem 19 is connected to the slidable plunger 37 of asolnoid 38, and hence it will be seen that the stem is drawn down to operate the ejector 12when the solenoid is energized.

The circuits of the solenoids 38 are con trolled by'switches eonsisting'of contacts 39 carried by the auxiliary'bars 30, andeach,

positioned opposite another contact 40. Each contact 40 is carried by a rocker arm 41 pivoted intermediate its ends, as shown at 42, to a post 43 on the support. 22. To the end of the arm 41 opposite the end carrying the contact 40 is connected a spring 44 anchored to the post 43. On the same side of the rocker arm 41 as the spring 44 is a lug 45 which engages the post 43 and thus limits the swing of the contact 40 toward contact 39. The contacts '40 are all mounted on a bar' 46 of insulating material carried by a pair of the hereinbefore described rocker arms 41. Each pair of contacts 39 and 40 is wired to a solenoid corresponding to ejector mechanism which is controlled by the respective bars 30.

It will be evident from the foregoing that when a key 23 is depressed to depress one or more auxiliary bars 30, the circuits of corresponding solenoids 33 are closed, whereupon the stems 19 connected to the plungers 37 of said solenoids and the bars 27, but not the auxiliary bars 30, are drawn down to operate the ejector or ejectors 12 connected to said stems.

An angle-beam 47 is secured across the casing 10 to provide bearings 48 for a rock shaft 49 having U-shaped bends 50 closed on one side by soldered plates 51. A bend 50 is opposite each rod 32 and a'finger 52 extends from said rod into the nose of the bend. These parts have no function, ordinarily, but'when the electric actuating means are out of order the shaft 49 is rocked in a clockwise direction as viewed in F 3, by means of the crank-handle 53 connected thereto on the outside of the casing 10, whereby, through the parts 51 depressing the fingers 52, all the auxiliary bars 30 are lowered out of reach ofthe key stems 24. This action, of course closes the circuits of the solenoids at the contacts 39 and 40 and depresses the rocker arms 41, but the circuits are broken at another point as follows:

On the beam 47, and insulated therefrom is a contact 53, and the shaft 49 carries an insulated contact 54 on one of the bends 50. These contacts are normally together, but they-are separated when the shaft 49 is rockedas hereinbefore described. The con.-

tacts 53 and 54 are wired to the main feed connection of the solenoids 38, and hence it will be seen that the latter cannot be energized when said contacts are separated. The machine can now be operated manually by pressing the keys 23 as usual. --The crank handle 53 has a spring latch pin55 provide'd withan actuating knob56,

and adapted-to enterkeeperfapertures in the casing "wall for locking the handle and-its shaft 49.

f lnthe operation of the machine, the

whereupon it is elevated by a key-lifting spring to separate the contact 39 from the contact 40 and break the circuit of the solenoid. The key-lifting springs are shown at 23* in Fig. 3. The solenoids operate at a very high speed, and hence a momentary depression of a key 23 suitlices to obtain a complete working stroke of the ejecting mechanism.
